Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 to 2, the utility model provides a dental high-speed mobile phone, which comprises a head assembly and a handle assembly 2 sequentially connected from left to right, wherein the head assembly 1 comprises a connecting pipe 3 and an inclined pipe 4 arranged at the upper left end of the connecting pipe 3, a core 6 is arranged in the inclined pipe 4, a wind wheel 5 is sleeved on the core 6, a button 7 is detachably fixed at the rear end of the inclined pipe 4, the handle assembly 2 comprises a handle pipe 9, a water inlet pipe 11 and a first air inlet pipe 10 are arranged in the handle pipe 9, a plug 15 is arranged at the rear end of the handle pipe 9, a first air inlet hole and a first air outlet hole are arranged in the connecting pipe 3, the first air inlet hole and the first air outlet hole are respectively arranged at the front side and the rear side of the wind wheel 5, the first air inlet hole is connected with the first air inlet pipe 10, a second air outlet hole communicated with the first air outlet, the plug 15 is provided with a second air inlet pipe 16, a water inlet 17 and a third air outlet, the second air outlet is communicated with the third air outlet, and the first air inlet pipe 10 is connected with the second air inlet pipe 16. The second air outlet hole is an inner cavity of the handle pipe 9, so that the inner cavity is larger than the first air outlet hole, the wind wheel 5 can conveniently rotate and discharge air by utilizing the negative pressure principle, and the handle pipe 9 can also be used as a heat radiation body to assist in heat radiation.
